Background technique
Exhaust brake is a kind of auxiliary braking mode generally applied, be mainly used in the driving cycle that haulage vehicle lower long slope etc. needs continuous braking power, improve braking force, the braking force caused because of the rapid warm raising of drag friction to delay the actuator in main service brake assembly declines, and ensures driving safety.
Current heavy-duty car exhaust brake relies on the exhaust brake butterfly valve be arranged on outlet pipe to realize, and when exhaust brake butterfly valve cuts out, performs exhaust brake and provides additional braking force, when exhaust brake butterfly valve is opened, removes exhaust brake and does not provide additional braking force.

(1) because exhaust brake and service brake are handled respectively, driver is difficult to the correct opportunity grasping exhaust brake, can not give full play to the interlock Braking efficiency of exhaust brake and service brake.
(2) because engine fuel oil system when being exhausted braking stops oil spout usually, if just remove exhaust brake when therefore braking is lower to the speed of a motor vehicle, motor is easily caused to recover accidental conditions, service brake may be affected, turn to the work with power assisting devices such as clutches, cause traffic safety.
(3) oil spout and the opportunity of recovering fuel feeding is stopped, by the fuel economy of impact braking motor coast period and exhaust emissions performance owing to being difficult to correct grasp.
(4) exhaust brake has a negative impact to service brake assembly braking force distribution after starting, and control can endanger the insensitivity of Vehicular system not in time, causes potential driving accident.
(5) when emergency braking, driver will handle exhaust brake switch and service braking pedal simultaneously, easily disperses driver attention, may lead to traffic accident.Time urgent, driver can forget and uses this auxiliary brake function, and switch opportunity is improper also can form harmful effect, causes potential driving accident.
The problem that after adopting, although a kind of form can avoid manual operation to bring, but because existing exhaust brake butterfly valve structure is simple, generally include a single-acting cylinder and returning spring, drive butterfly valve (butterfly plate) that opening and closing two kinds of working staties can only be formed, make that exhaust brake power is corresponding also only has maximum two kinds of zero-sum, therefore when exhaust brake butterfly valve ON/OFF, larger impact can be produced, both driving comfortability was affected, also can have a negative impact to the braking force distribution characteristic of vehicle, make the parts be connected with exhaust brake butterfly type valve reduce working life simultaneously.

The signal input part of described accelerator pedal sensor (24) connects the State-output circuit of gas pedal control loop, the signal input part of described brake pedal sensor (21) connects the State-output circuit of brake petal control loop, the State-output circuit of the signal input part connecting engine control loop of described engine rotation speed sensor (22), the signal input part of described rotating speed sensor for gearbox (23a) connects the State-output circuit of gearbox control loop, the signal input part of clutch pedal sensor (23b) connects the State-output circuit in Clutch Control loop, the signal input part of driving switch sensor (23c) connects the State-output circuit of gear control loop,
Wherein said controlling method comprises the following steps:
Each sensor continuous acquisition corresponding signal, controller receives the output signal of each sensor;
Controller generates the continuous state data of the output shaft of brake petal, gas pedal, motor and gearbox, clutch, gear;
Controller, according to onboard data transaction module process continuous state data, forms road conditions and braking intention judged result;
Controller exports relevant pressure control signal, controls the opening angle that electrohydraulic pressure control control valve regulates exhaust brake butterfly valve, regulates the braking force of exhaust brake;
Described butterfly valve of working as is in complete opening state:
S161, judging whether the first displacement data is passed and give, is perform S162, otherwise performs S104;
S162, judging that whether the first rotary speed data is higher than 1500rpm, is perform S163, otherwise performs S104;
S163, judges whether to be in neutral, otherwise performs S164, is perform S104;
S164, judges whether clutch engages, and is, performs S165, otherwise performs S104;
S165, controller, according to the first displacement data delivery pressure control signal, makes electrohydraulic pressure control control valve control exhaust brake butterfly valve and keeps butterfly valve to be in setting aperture; Formed and open with brake pedal status.
